    Abstract: PURPOSE:To manufacture the titled base material having uniform refractive index distribution in the longitudinal direction by heat-treating the porous glass base material in the specified conditions in the atmosphere contg. halogenides and helium. CONSTITUTION:A porous glass base material B consisting of silica fine particles contg. the oxides of Ge, P, B, Al and Sb or the like as a dopant is quickly inserted into the inside of a heating furnace A wherein the gas contg. halogenides (e.g. SOCl2) and helium is flowed therein till the position in which the tip C of the base material B reaches
